在Golang中定义包含切片的数组的映射

In Go (golang), is it possible to define a map from strings to arrays, and in each array element I want to store a slice. Like this:

var data = make(map[string][2]Slice[]float64)

Then I want to retrieve my data, something like this:

floatValue0 = data["string-key"][0][#]
floatValue1 = data["string-key"][1][#]

data := map[string][2][]float64{"golang": {[]float64{3.14, 3.15}, []float64{3.12, 3.16}}}

fmt.Println(data["golang"][0][0])

output: 3.14
